In an effort to improve facial recognition technology -- and prevent wrongful identification based on built-in biases -- Microsoft is establishing a code of conduct for this technology and is asking other companies to join in. Microsoft President Brad Smith says in TechCrunch that having cohesive rules in place is the most responsible way to implement facial recognition technology. This Code of Conduct is in response to a test of facial recognition software systems run by the American Civil Liberties Union and other critics who found that, for example, the software incorrectly matched the photos of 28 US lawmakers with mug shots of convicted criminals.
